I have to second Torsten. I use the same setup for ages. It works
flawlessly without any problems. Cygwin is well integrated into the
Windows environment. You can easily call Win apps from Cygwin or vica
versa. In fact, my standard shell is Cygwin's bash.

I don't see any downloaded files, but I also had a issue at a specific
moment with tlmgr I can't remember.

Using a wrapper script solved at least my problem

#!/bin/bash
#
tlmgr.bat "$@"
